Correction of a Class II deep overbite skeletal and dental asymmetric malocclusion in an adult patient

Treatment of a Class II malocclusion with deep overbite in an adult patient using intermaxillary elastics and spee curve controlling with reverse and accentuated archwires

“…It happened because it is an adult patient and he was out of growth. This result is compatible with several authors;[ 19 25 28 ] however, another researches[ 26 27 ] found different results, showing a general tendency to maxillary and mandibular mesial movements.…”

“…One of the considered treatment options were the first maxillary premolars and right second mandibular premolar extractions,[ 18 19 ] applying, this manner the appropriate orthodontic retraction mechanics and this way correcting Class II malocclusion and the left dental midline shift; however, this technique would take as side effect a greater difficulty to control and reduce the deep overbite, allied an unfavorable facial pattern and profile. All these factors advised against this treatment choice, besides the fact that there was not anterior dental protrusion and the patient has a passive lip sealing.…”

“…In the skeletal relationships, there was an increase in the mandibular plane measurements, evidencing a lower anterior facial height increase and a mandibular clockwise rotation, due accentuated and reversed archwires to flattening the curve of Spee, which lead to premolars extrusion, reducing overbite, and consequently increasing facial height, results also compatible with several authors. [ 14 19 24 26 29 ] In the other side, are Ferreira[ 28 ] and Vaughan[ 25 ] that found no great vertical changes in their CDABO case reports.…”

Soft tissue, skeletal and dentoalveolar changes following conventional anchorage molar distalization therapy in class II Non-growing subjects: a multicentric retrospective study

“…There are several strategies to correct class II malocclusion in adult patients. Premolar-extraction treatment, 11,30 fixed functional appliances, 12,13 and orthognathic surgery 14,15 are most commonly used, whereas distalizing maxillary molars at growth completion might not be considered a conventional procedure, due to the difficulty of moving the maxillary molars distally after full eruption of the maxillary second and third molars, 2 and because mandibular growth cannot be expected. As confirmed by our findings, ANB angle was not subjected to significant changes during treatment.…”
